VALVE.

Original application filed May 11, 1918, Serial No. 233,905.

be advantageously used in connection with the heating system for railway cars. The invention was first disclosed in my co-pending application Serial No. 233,905, filed May 11, 1918, of which this application is a division.

One of the principal objects of this invention is to provide a valve adapted to be con nected to and control three heating units, a

single valve member being employed to selectively place one, two or threeof said heating units in operation.

The invention will be more readily understood by reference to V the accompanying drawings, in which,

The valve herein illustrated is intended primarily for use in controlling the supply of steam to a plurality of radiators. These radiators are indicated generally by the let ters A, B and C. The radiator A may be said to be primary, while the radiators B and C are secondary. It is desired in the use of a system of the character to which the valve has been applied, that heating fluid should first be supplied to the primary view on Specification of Letters latent.

Divided and this application filed February Serial No. 278,882.

diverting the flow of heating fluid into either one or bothof the secondary radiators as desired. Where the invention is employed lI1 COI1I16CtlOI1 with a heating system which ut lizes vapor or steam at atmospheric pressure, the pipe in the upper right hand corner of Figs. 5, 6 and 7, will be connected to a thermostatic controlling device of the type such as illustrated, for example, in the patent to Gold, No. 987,569, the operation of which is well understood.

The device of my invention comprises a casing which is divided by interior webs 10, 11, 12, 13, 14 and 15 into six chambers 16, 17, 18, 19, 20 and 21. These chambers are provided with inlet ports to which pipes 22, 23, 24, 25, 26 and 27 are connected; the pipes 22, 27, constituting a part of the radiator A, pipes 23, 26, constituting a part of the radiator B and the pipes 24, 25, a part of the radiator C. The pipe 22, constitutes the inlet for heating fluid, so far as the valve is concerned, while the pipe 27, constitutes the outlet or discharge passage.

The valve member comprises a cylindrical member adapted to snugly fit the walls formed by the webs 10 to 15 inclusive and consists of a lower disk 28 which rests on the bottom wall 29 of the valve casing, an upper disk 30 to which a valve stem 31 is rigidly secured and two vertical webs 32, 33, which extend between the disks. The valve member is thus provided with three trans verse passages which are designated X, Y, Z.

The valve casing is provided with an upwardly projectingannular flange'34, internally threaded and adapted to be engaged by a bonnet 35, a spring 36 being interposed between the bonnet and the upper disk 30 of the valve member. A gland and suitable packing serves to prevent leakage around the valve stem. To the upper end of the valve stem 31 is secured a crank 37 connected stops serve to limit the movement of the c in a cylindrical projection 51, formed. on the valve casing. A helical spring 52, is interposed between the head, of the locking member and av screw plug 53 which has threaded engagement with the interior of the cylindrical projection 51.

with.

. The loweridisk 28 of the valve member is formed with aperforation 54 at one side of the web 33 and another perforation 55' between the webs 3:2, 83. The bottom wall '29 of thecasing, is formed with a perforation 56, as best sh'owninFig. 9 and with an arcuate .channel 57 in communication there- The openings as described serve to permit the escape of water when in communication with the passages through the valve member in a manner more fully described hereinafter. The web-10 between thechambers 16, 21, is preferably provided with a small perforation 58, near the bottom there of through which the water of condensation from the radiator A is permitted to pass, even though the valve is in a positionto direct steam through one or-both of the secondary radiators.

In describing the operation of. the valve it will be assumed that it is intended to conentering through pipe 22 passing directly,

through the valve member into thedischarge pipe 27. In this position of the valve member both the radiators B and C are in communication with the water outlet 56, by

reason of the register of the openings 54,

with the groove 57 and. outlet 56 respectively.

In theposition of Fig. 5 (which will refer'redto as the second position), the

' steam. entering through the pipe 22 passes into the radiator Bthrough the valve member and emerges from the pipe 26 thereof,

then passes through the passage Y of:the

valvememberinto the discharge pipe. 27 of radiator A. In this position of the valve inember' the radiator C is inactive and any water of condensation may escape through the apertures 54 and 56 which are in register. 7

With the valve member in the posit-ion of Fig. 7 (hereinafter referred to as therthird position), it will be seen that steam admitted through the pipe 22 enters the chamber 16 and is directed through the'passage ofthe valve member into the chamber 17, V thence through the pipe 23 representing a coil of the "radiator B. After. passing through radiator B, the steam emerges from the pipe 26 into the chamber 20, thence through the passage Z of the valve member into thechamber 19, thence into the pipe 25 constituting a part'of the radiator C; Any remainingsteam emerges from the pipe Q after passing through radiator G into the chamber 18, thence through the-passage Y of the valve member into the discharge chamber 21, thence into the discharge or outlet pipe 27. In this position of thevalve member it will be seen that the outlet port 56 for draining is covered, any water of condensation being caused to pass through the valve into the discharge pipe 27. V

The operating crank and connections with the valve may be arranged tosuit different conditions. Thearrangement shown is that which I have adopted for controlling heat in railway cars, particularly railway sleeping cars. In the position of the parts shown in Figs. 1 and 2, the valve member will be in the position of F ig. 6, the other position of the valve being indicated on the bracket shown in Fig. '2. f Y Y In certain of the claims hereof I have employed the reference numerals andrletters ofthe drawings to indicate certain chambers and ports. This is done as a matter of convenience andto avoid prolixity, and is not intended to limit the invention to the precise structuralfeatures of the embodiment of the invention shown.
